Abstract
Through the use of a multi-body system (MBS) for the cyclist and DXF model for the car, realistic results
can be expected with regard to the complex movement process and the throwing distance of the cyclist
by using the computational simulation of a car-cyclist-collision in PC-Crash.
The comparison of measurement data from crash tests with the simulation results in PC-Crash has showed that the collision sequence and thus also the throw distance of the cyclist must not to be reproduced realistically. In this work the sources of error in the simulation of car-bicycle collisions in PC-Crash were analysed and
optimization possibilities were presented. In the result it is always necessary to adapt the real circumstances of an accident and, if necessary, to modify the passenger car-DXF model in order to obtain realistic results. The adapted and verified MBS and DXF models as part of this work can be regarded as a suitable tool to limit the collision speed of an accident car based on the throwing distance of the cyclist.
